Abstract: The present invention is a companion unit and companion system. The companion unit comprises an UAV that further comprises one or more of the following elements: propulsion units, circuit boards, navigation sensors, cameras, speakers, microphones, chassis, processors, and batteries. The companion system comprises one or more bases wirelessly connected to the companion unit and in possibly to one or more computer devices and/or to the Internet. The elements thereby facilitate one or more of the following Internet connectivity, wireless local area network (WiFi) connectivity, computer device connectivity (e.g. connectivity to a cell phone, a smart phone, a laptop, a tablet, a smart television, a WiFi enabled appliance, or any other computer device), base connectivity, and cloud storage connectivity. The companion system and/or the companion unit is connected to an artificial intelligence module. The companion unit and system are programmed to function as a companion to a human user.

Abstract: A system is provided comprising an automatic toy tracking system adapted to track an infrared signal emitted by a remotely controlled toy vehicle. The tracking system has a series of infrared receivers and is adapted to pivot and rotate in response to the relative intensity of the infrared signal received by each receiver. When the tracking system has positively ascertained the location of the infrared emitter, the tracking system can be adapted to fire at least one projectile at the toy vehicle.
